||Environmental assessment of aerosols, bioaerosols, and airborne endotoxins in a machining plant
||Dec. 1996, Vol.57, No.12, p.1163-1167. Illus. 14 ref.
||Bioaerosol monitoring was undertaken at eight machining sites and one assembly site in an engine plant. The machining sites represented areas supplied with three different metalworking fluid (MWF) formulations. Bulk in-use MWF samples were collected at the machining sites and compared with air measurements. Gravimetric concentrations of MWF aerosol in the air were all less than 5mg/m3 and were significantly higher on the older engine line with fewer engineering controls. Airborne levels of endotoxin were strongly correlated with the bulk MWF endotoxin concentration and were particularly high when microbial growth in MWF was excessive. Levels of endotoxin in these plants may exceed the thresholds previously identified for acute respiratory health effects.
